Explanation:
Detailed explanation-1: -Porins are involved in the exchange of nutrients over the outer membrane of Gram-negative bacteria but are also involved in pathogenesis. The present review will focus on the description of the structure and the role of Gram-negative bacterial porins in the bacteria-host interactions.
Detailed explanation-2: -Porins are pore proteins contained in the outer membrane of Gram-negative bacteria and they mediate the diffusion of small hydrophilic molecules.
